This is a great question with a lot of different answers. The best place to start is by thinking about your personal networks and who might be able to help you. Friends and family are often a great starting place, as they may be willing to invest smaller amounts of money to help get your business off the ground. You can also look into angel investors, which are typically affluent individuals who provide capital for early-stage companies in exchange for equity. There are also a number of venture capital firms that invest in startups, though these tend to be more focused on companies with a proven track record and solid growth potential.
Another option is to bootstrap your startup by self-funding it with your own savings. This can be a risky proposition, but it can also be a great way to get your business up and running without giving away equity or taking on debt. Whatever route you decide to take, be sure to do your research and put together a solid business plan before moving forward. Good luck!
